在liferay主题(速度模板)中使用自定义服务或liferay服务? [英] Using custom services or liferay services in liferay themes (velocity templates)?

问题描述

如何在init_custom.vm，portal_normal.vm等速度文件中的liferay主题中使用自定义服务方法.

How to use custom services method in liferay themes in velocity files like init_custom.vm, portal_normal.vm etc.

我看到liferay为 GetterUtil 等github.com/liferay/liferay-portal/blob/master/portal-web/docroot/html/themes/_unstyled/templates/init.vm"rel =" nofollow> init.vm 文件.

I see liferay provides a lot of variables of helper utility classes like $portalUtil for PortalUtil, $getterUtil for GetterUtil and so on, inside the init.vm file.

是否可以从UserLocalServiceImpl获取我的自定义服务的实例，例如com.my.custom.service.MyCustomLocalServiceImpl的实例还是liferay的服务?

So is it possible to get instance of my custom services like an instance of com.my.custom.service.MyCustomLocalServiceImpl or services of liferay from UserLocalServiceImpl?

以下是一些伪代码，以说明我需要什么:

Here is some psuedo code, to give an idea of what I need:

// this code calls method from MyCustomLocalServiceImpl class to fetch items
#set ($listOfItems = $myCustomLocalServiceUtil.getAllItems())

// this code calls method from UserLocalServiceImpl class to fetch users
#set ($listOfUsers = $userLocalServiceUtil.getUsers(0, 99))

环境:Liferay 6.1 CE GA1

推荐答案

可能.

1. 以下代码显示了如何获取服务:

1. The following code shows how to get the services:

// Fetching instance of my custom services
#set ($myCustomLocalService = $serviceLocator.findService('myCustomServices-portlet', 'com.my.custom.service.MyCustomLocalService'))

// Fetching instance of UserLocalServiceImpl
#set ($userLocalService = $serviceLocator.findService('com.liferay.portal.service.UserLocalService'))

然后只需调用服务方法:

Then simply call the service methods:

#set ($listOfItems = $myCustomLocalService.getAllItems())

#set ($listOfUsers = $userLocalService.getUsers(0, 99))
